noisy, boisterous
喧 centers on loud, energetic noise: a boisterous, clamorous atmosphere. The two given meanings are close synonyms describing the same kind of noisy disturbance.
喧 combines 口 (mouth) with 宣, which likely contributes the sound and the idea of spreading or proclaiming. Together they suggest loud voices spreading noise.
A mouth 口 beside 宣, which looks like a roof over a sun-like shape. Imagine a mouth under a roof shouting so loudly that the noise spreads everywhere, making the place boisterous.
For ケン, picture a noisy crowd at a kennel where all the dogs are barking: kennel -> ケン, and the barking makes the scene boisterous.
